Dose limiting toxicities (DLTs) includes the following: * Grade ≥ 3 drug related adverse event (AEs). However, fatigue, nausea/vomiting adequately treated with anti-emetics, endocrinopathies adequately controlled with one physiologic hormone replacement, skin toxicity and single laboratory values out of normal range without any clinical correlate, asymptomatic grade ≥3 lipase or amylase elevation, tumor flare defined as local pain, irritation, or rash localized at sites of known or suspected tumor or a transient Grade 3 infusion adverse event are excluded. * Liver function test abnormality: * AST or ALT \> 5 x ULN * Total bilirubin \> 3 x ULN * Concurrent AST or ALT \> 3 x ULN and total bilirubin \> 2 x ULN * Drug related AE requiring treatment interruption for more than 2 weeks

Percentage of participants whose best overall response is either a Complete Response or a Partial Response according to Response Evaluation Criteria In Solid Tumors (RECIST v1.0) criteria over the the total number of evaluable participants. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT/MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.", or similar definition that is accurate and appropriate.

PFS is defined as the time from the date of randomization to the date of first documented tumor progression or death due to any cause, whichever occurs first. If a participant has not had a PFS event at the cut-off date for analysis or at the date when a further antineoplastic therapy (other than those planned as study treatment in the protocol) is started, PFS will be censored at the date of last evaluable tumor assessment before the cut-off or start of further antineoplastic therapy.
